AquaCrop Model Validation for Simulating Biomass and Water Productivity Under Climate Change for Potatoes

Effective crop development modelling is essential for management, water resource planning, assessing climate change's influence on agricultural production, and yield prediction. Validation simulation of the measured data indicated that AquaCrop software an effective reliable program designing pressurized irrigation systems to increase application efficiency, system performance future The model was evaluated through a solid-set sprinkler surface drip at 100%, 80%, 60% evapotranspiration (ETo) potato crop. has shown better simulate growth predicting variables under various systems. drip-irrigation system's 80% ETo (48.00, 8.05 ton ha-1) Yield had substantial impact productivity (WP), matching potatoes irrigated with sprinklers 100% (37.39, 7.19 ha-1), 20% savings. Attributes (canopy cover, biomass, factor (Kc), productivity) were affected by increasing deficit. simulated little higher than observed treatment, but still similar deviation, it slightly lower seen treatment mid-season. predicted biomass correctly when adequate. results there may be some changes in operations over years based method.
